What is the history of QR codes?
The history of QR codes can be traced back to 1994 when the first QR code, which was an early form of a barcode, was created by Japan's Denso Wave, a subsidiary of the Toyota Group. The QR code was developed as a way to quickly and accurately keep track of parts during assembly. Denso Wave eventually released the QR code to the public in 1999, allowing other companies to use the technology.
QR codes soon spread across Japan and began to be used in marketing and advertising campaigns. QR codes were used in Japan to encode URL addresses, however, they were not adopted by US marketers until the mid-2000s. By 2010, QR codes had become popular in the US, appearing on everything from advertisements to restaurant menus. Today, QR codes are used in a range of industries, from retail and healthcare, to education and entertainment.
What is the history of paper lanterns?
Paper lanterns, or lampshades as they are sometimes known, have been dated back to as early as 200BCE in China during the Han Dynasty. They were made from washi paper, which is made from various plants such as mulberry, bamboo, and gampi. Initially, they were used as lighting for religious and ceremonial purposes, but in the late sixth century, the designs and sizes became more varied for more decorative purposes. In the eighth century, paper lanterns were being made with different colored papers, some of them being embroidered for increased splendor. During the Song Dynasty, lanterns reached a high level of intricacy with pieces made of many different colors and materials.
By the tenth century, paper lanterns were also being used for decorative purposes in the home, during material celebrations, and in the street during festivals. The Chinese later introduced the technology of oil lamps, which gave lanterns a longer burn time duration and increased the popularity of paper lanterns.
In the 18th century, paper lanterns were introduced to Japan and Europe. They were used mostly during celebrations and festivals and were often given as gifts or hung as decorations. In the mid 19th century, electric lamps became available, however, paper lanterns continued to be popular up until the late 20th century when they were eventually replaced with modern lighting fixtures.
Today, paper lanterns are still popular in decorations for parties, festivals, and special events. They have been known to represent luck and good fortune around the world.
